ROBERT L. PAULSON, OF BROOKLYN, NEW YORK.

SMOKE-UPTAKE.

Original application filed October 24, 1912, Serial No. 727,553.

T0 all whom it may concern Be it known that I, ROBERT L. PAULSON, a citizen of the United States, and resident of the borough of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Smoke-Uptakes, of which the following is a specification.

This invention relates particularly to a smoke-pipe or uptake for self-leveling gal- The subject matter hereinafter described is a division of an application filed by me on the 24th day of October, 1912, and bearing the Serial No. 727,553. In the last named application I have claimed the general construction of the stove, whereas in the present application I direct my claims tonovel compensating means for the. differential movements of the smoke pipe and stove.

The object of the invention is to provide a simple and compact device for the purpose set forth, which canbe easily. manufactured as well as readily assembled or disconnected. Further objects and advantages will become apparent as the description proceeds.

the aforesaid objects in View the in vention consists in the improvements and combinationsof parts hereinafter described modified form of the invention; Fig. 4: is a in their preferred embodiments illustrated on the drawings hereto annexed, and pointed out in the appended claims.

In thesaid drawings: Figure lis a front view of the uptake, a general outline of the stove being shown; Fig. 2 is a vertical sec tion of the uptake illustrated in Fig. 1, a'

portion of the stove being broken away; Fig. 3 is a fragmentary front view of a and gases of combustion pass out from the stove at 13.

A member 16 is fixed to the stove 10 over the smoke outlet 13 thereof. This member is hollow so as to constitute a continuation of the smoke-flue. It is formed with circularly curved sides 17 and straight or flattened front and rear Walls 18, 19. Basal Specification of Letters Patent.

Patented Aug. 25, 1914. Divided and this application filed August Serial No. 786,683.

flanges 20 extend endwise from a lower neck portion 21 of the member 16, and bolts 22 passing through the flanges serve to fasten the said member in position on top of the stove. The upper part of this fixed or rela-, tively stationary member is cut away as at 23, after themanner of a. segment, on a line substantially parallel with the base. Pivot bolts 24 are threaded into the front and rear wallsv 18, 19, centrally with respect to the circularly curred sides or end walls 17. The bolts 2a terminate flush with the inner faces of the said walls 18, 19 of the stationary member 16 so as to avoid burning of the inner ends thereof and toafford an unobstructed passage for the flue-gases. Pivotally supported on the said bolts 2% is an upper movable member 30, constructed to take over the stationary member 16 on all four sides thereof. The said fixed member stops short of the highest inside part of the movable member 30, and therefore the smoke can at all times find its way out through a neck 31 with which the upper portion of the latter member provided, irrespective of the relatively different positions of the stationary member and the stove. The opposed outer side edges 32 of the said movable member 30, terminate on a diametral line 14 passing through the central bolts 24, so as to provide suflicient clearance with respect to the lower neck 21 of the said member. By virture of the coa'espondingly' shaped straight or flattened front and back walls on both the stationary as well as on the movable member, it becomes a comparatively easy matter to disconnect these parts by simply removing the pivot bolts 24:. The upper neck 31 of the movable member 30 is surrounded by a sleeve 33, and the space included by the latter, the neck 31 and a bottom 34.- joining them together constitutes an annular chamber which forms the lower part of a slip or telescopic joint. The comsmoke opening in the side partition or wall of the kitchen or galley, the said pipe ll forms a right-angular extension or elbow 45. Adjacent to the place where the pipe passes, the elbow is provided with a rim 46. A retaining flange 47 having a 4-8 for the reception of the said rim l6, holds the pipe in position while it permits oscillatory movement thereof. In order to facilitate assembling of the parts, the flange 4:7 is split, or in other words, it is formed of two semi-circular parts which are held to the wall or other primary supports by bolts A9.

In the modification of the smoke-uptake illustrated by Fig. 3, the cooperating stationary and movable members 16 and respectively, are held in an inverted position. In this instance, the slip joint may be formed on the end of the pipe 41. This construction can be advantageously employed when the exit for the smoke pipe passes vertically through the reel? or ceiling of the galley instead of horizontally through the wall as indicated in Figs. 1 and 2.

VVhi'le I have shown the preferred embodiment of my uptake connection it will be understood that numerous substitutions of equivalents can be made therein without departing from the spirit of the invention.

Having described my invention what I desire to secure by Letters Patent and claim is:

1. A compensating smoke-uptake for selfleveling stoves, comprising in combination with a stove, a smoke outlet having a pivotal connection with the latter, a telescopic joint above said connection, an elbow having a rim, and a retaining flange behind which said rim is free to rotate.

2. A compensating smoke-uptake for sell leveling stoves, comprising in combination with a stove and the smoke outlet thereof, a relatively stationary member having its lower portion secured to the top of the stove over its said outlet, a movable member pivoted concentrically to said stationary member and provided with an annular chamber, and a smoke pipe having its lower end in telescopic engagement with said chamber.

3. A compensating smoke-uptake for sellleveling stoves, comprising in combination with a stove, a member fixed to the latter and having straight front and rear sides and curved ends, a semi-circular member taking over said fixed member and pivoted to the straight sides thereof equidistantly from its said ends, a neck extending from the top of said movable member, a sleeve spaced from the outside of said neck and providing an annular chamber therewith, and a smoke pipe having its lower end telescopically received in said annular chambe.

i. A compensating smoke-uptake for selfleveling stoves, comprising in combination with a stove, a member fixed to the latter and communicating with the flue thereof, said member having flattened front and rear walls and curved ends, a correspondingly formedmovable member adapted to take over the outside of said fixed member, bolts threaded into the flattened sides of said latter member on which the movable member is pivoted equi stantly from said curved ends, the upper part of said movable member being formed with an annular chamber, and a smoke-pipe having its lower end in telescopic engagement with said chamber and the other end free to follow the motions of the stove.

A compensating smokeuptake for selflevcling stoves, comprising in combination with a stove, a hollow member fixed to the latter, a correspondingly formed movable member taking over said fixed member and pivoted concentrically thereto and provided with an annular chamber, a smoke-pipe having one end in telescopic engagement with said chamber and its other end formed with an angularly oliset portion, and means for securing said portion rotatably in position on a primary support.

(3. A compensating smoke-uptake for selfleveling stoves, comprising in combination with a stove a smoke outlet pivotally connected with the latter and provided with an annular chamber for packing material, a vertical smoke-pipe having its lower end slidably received in said chamber, the other end of said pipe extending horizontally, a rim on the horizontal end of said pipe, and a split retaining flange recessed to take over said rim, the same securing the pipe to a primary support while permitting oscillatory movement thereof.

Signed in the borough of Manhattan in the county of New York and Satate of New York this 22nd day of August A. D. 1913.
